display-protocol -> library/protocol/display/, scanout-protocol ->
library/protocol/scanout/. Consumers import both directly, killing the cryptic
dp/sp aliases in virtio-gpu (now display_protocol / scanout_protocol) and the
runtime.display_protocol / runtime.scanout_protocol re-exports. runtime.display
(the client) still imports display-protocol by name; scanout has no runtime
client, so its runtime module import is dropped too.
zig build + test green; display-service, virtio-gpu, display-native,
display-reattach pass.
device-manager-protocol -> library/protocol/device-manager/. Its consumers
(pci-bus, usb-xhci-bus, the acpi discovery service, device-manager, device-list,
crash-test, and the not-yet-built intel-integrated display sub-driver) import the
module directly instead of through runtime.device_manager_protocol, which is
deleted. runtime.device_manager (the hello client) already imported the module
by name and is unchanged.
zig build + test green; device-manager, driver-restart, device-list, pci-scan pass.
